in sonic licor constructions comprising also priniiny upper transverse sections, and especially where tlie longitudinal sections are Very long proportion to their Width.

E prefer to also connectl tlie longitudinal scctions side by side @is sliown in l0, in addition to securing their ends in the ninniier illustrated in Fig. l1; sucb e. toor is illustrated in section in Fig. l2, and one of t-iie designs wliere this construction is Well adeod is shown in a, reduced scale in lliy interlocking iioor cen be made of any suitable' material besides Wood, its construe tion being also Well suited for rubber tiling end flooring, composition, and the like;

therefore l do not-wish to liinit myself to :'vlie use of any particular material.

From tlie foregoing it is seen that l pro! fide i novel construct-ion of interlocking doors, and novel ineens for joining tlie dii?- erent elements composing tlie saine; in the nrious arrangements described, the lower sections are used tol retain the runners, and tile upper sections lire retained thereby, llie season for this is that, assuming that. tiie upper sections be niadev of liner and costlier inaterial,tlie thickness oi tlie seine will have to beI kept as much es possible Within narrow limits; it is therefore better tluit tlic interlocking part oii tlie same be constituted by tlie dove-tailed male section, in wliicli the inner points are tlie strongest. @n the otlicr lisnd it con be seen, that. in order to provide liool joint sucli as adopted in connection Witli tile lower sections having ilie saine strength, it 'would Voe necessary to use a tliiclrer ineteu riiil. it is obvious however, tliiit the wuys l t' joining t-lie upper and lower sections con inverted, u'itln'nit materially departing 'oni tlie spirit oil iny invention. My 'ninfgljlilcoi' is also suitable for being;j asace with single runners suc-li nl, 2S; and in this connecltlie saine direction;

tion il' may also be stated, that since the lower ections :ire tlie first ones to be laid down, it is preferable that. tlie sume be used to ret-ain in positionilie extrt Aloose runners, inasiiiucli tlic 'tact that tlie runners cannot free themselves Yfrom ille elementary sections one oi' tlie important factors-in insuring tlic ease und speed Vin tlie operation.

Having thus described and ascertained tlie nature of niy invention, what I clain'i as non', and desire to secure by Letters lnalient or" the United States is:

l. iioo'r coinuosed of group sections, each comprising' two side runners. a strata ci' primary buse sections having their lower face lusli with the lower face of said runners, and li sti-ata 01' primary upper sections lyingv directly on said base sections, said two strata oi primary sections being` jointly interlocking with, and retained by said runners; substantially :is set-forth.

A `floor composed of a plurality of runners, u strata of primary base sections liaringv tlieii' lower face iusli with tlie lower face of seid runners interlocking with, and retaining said runners in a i'iried relation to eacli other, und zi strata of primary upper sections lying directly over said bese sections interlocking with, and retained in position by said runners; substantially es set forth. p

3. in an interlocking licor, a plurality of longitudinal primary sections forming an even surface and interlocking side by side, their sides being ,formed -with reciprocally interlocking liook iornied tenons and grooves, the outer face of eacli of said teno'ns and tlie inner face of each of said grooves being` substantially at iiglit angles to the surface of said sections, and the inner face of said tenons and tlie outer face 'of encli of said grooves registering tlierewith being.;r inclined so as to iiorin o dovetailed goiiit; substantially :is set forth.

e. A loor coiiiposed of a. plurality of independent group sections, eacl'i comprising two side runners provided with a groovel along their inner surfaces having two sides inclined in about tlie saine direction, a plurality of primary base sections provided witli tenons registering` with t-iic lower part of said grooves, and a plurality of primary upper'sections providedwitli tenons registering with the remaining portion of said grooves; substantially as setiortli.
